Now then, done a few extract brews from brewuk as they have extract kits with instructions. My question is the amount of priming sugar, I have been doing the usual half teaspoon per pint and the brews are good but the pendle witches brew says it needs an additional 330g of sugar I presume for priming but it's only an 18 litre brew so seems a lot of sugar for priming? So am I right with the half teaspoon per pint or is more needed ?
